HUIBIER'I B. HUMP HRLEY, OF KALAMAZOO, MICHIGAN, ASSIGNOR TO GENERAL GABI LIGHT COMPANY, OF KALAMAZOO, MICHIGAN.

GAS HEATER.

Application filed October 25, 1922. Serial No. 596,900.

To all whom it may concern: 9

Be it known that I, HUBERT R. HUM- PERRY, a citizen of the UnitedStates, residing at the city and county of Kalamazoo, State of Michigan,have invented certain new and useful Improvements in: Gas Heaters, ofwhich the following is a specification. This invention relates toimprovements in gas heaters. V The main objectsof this invention. areFirst, to provide an improved combined fire back and radiating elementfor gas heatby the devices and means described in thefollowingspecification. The invention is clearly defined and pointed out in theclaims,

A structure which is a preferred embodi ment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisapplication, in which:

Fig. I is a front perspective view of a gas heater embodying thefeatures of my invention, the embodiment being in a portable heater.

Fig. II is a detail vertical section on a. line corresponding to line2-2 of Figs. I, III and IV.

Fig. 111' is a detail view, partially invertical section on a linecorresponding to line 3-3 of Figs. II'and IV.

Fig. IV is an inverted view of my combinedfireback and radiatingelement.

Fig. V is a front elevation of a gas heater embodying my inventioninstalled as a wall heater.

Fig. VI is a detail vertical section on a line corresponding to .line6-6 of Figs. V and VII.

Fig. VII is a detail horizontal section on a line corresponding to line7-7 of Fig, VI.

In the drawing the sectional views are taken looking in the direction ofthe little arrows at the ends of the section lines and similar numeralsof reference refer to similar parts throughout the several views.

Referrin tov the drawing, I have in Figs. 1', II and I I shown myimprovements embodied in a portable heater of thet pe shown in theapplication of Alfred H. umphrey, Serial No. 339,917, filed November 22,1919, in which a base 1 is provided having an upright or standard 2 onwhich the body 3 of the heater is pivotally mounted at 4.

The .body 3 is formed as a sheet metal stamping and comprises, back,top, bottom and side walls formed of the continuous outturned flange 5.The burner 6 is mounted below the body and is provided with a pluralityof tips 7.

My improved combined fireback and radiating element consists of the rearwall 8 of substantial thickness and body constituting a fire back forthe heater. The reticulated front 9 is connected'or formed with the backwall being connected thereto through the integral bosses or tie members10. These are preferably arranged in'vertically aligned space 13 betweenthe front and rear walls.

Spinelike projections 14 are. provided on the back, these projectionsbeing in them er become incandescent combustion cha and add not only tothe appearance but to the efiiciency of the heater.

The fireback and radiating element'fits within the body walls, the rearwall having flanges 15 at its side edges and a flange 16 at the top.

In the embodiment shown in Figs. V, VI and VII the heater body isprovided'with openings 17 at the top so that the product of combustionmay pass through the open ings 18 of the top flange 16. This embodimentis especially designed to be mounted or fitted in a recess 20 in a wall,as 21, there being a flue 22 in the Wall provided with a hood 23 at theup with the exception of the holes 17 in the top wall of the heaterbody, a bracket 24 being substituted for the base 1 torend'er thestructure more compact and properly support it within the recess.-

My improved heater is very efiicient and at the same time is attractivein appearance. The fragile part, or combined fire back and radiatingelement which is formed of earthy material is supported so that it isnot likely to be broken in handling, as in assembling or after assembledin the heater.

I have illustrated and described embodiments of my invention which Iconsider very practical. I have not attempted to illustrate the variousadaptations and modifications which might be desirable to adapt myimprovements to various types of heaters to which they are applicable,as I believe the disclosure made will enable those skilled in the art towhich my invention relates to embody or adapt the same as may bedesired.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a gas heater, the combination with a bined fireback and radiatingelement fitting within said body with its edges in contact with thewalls thereof and consisting of a rear wall constituting a fireback anda foraminate front wall integrally connected to said rear wall by spacedtie members disposed in vertical rows between the openings in the saidtop and bottom walls of said body, and a burner provided with tipsaligned with said openings in said body walls.

2. In a gas heater, the combination with a body member comprising back,top, bottom and side walls. of a combined fireback and radiating elementfitting within said body 4 with its edges in contact with the wallsthereof andconsisting of a rear wall constituting a fireback and aforaminate front wall integrally connected to said rear wall by spacedtie members, and a burner provided with tips directed between said frontand rear walls.

3. In a gas heater, the combination with a body, of a combined firebackand radiating element consisting of a rear wall constitut 55 ing afireback and a foraminate front wall integrally connected thereto byspaced tie members disposed in vertically aligned rows,

the face of said rear wall having a plurality of projections thereonbetween the tie mem-' bers, and a: burner provided with tips directedbetween the rows of tie members.

4. In a gas heater, the combination with a body, of a combined firebackand radiating element consisting .of a rear wall constituting a firebackand a foraminate front wall integrally connected thereto by spaced tiemembers, and a burner provided with tips directed between the rows oftie members.

5. In a gas heater, the combination with a body, of a combined firebackand radiating element consisting of a rear wall constituting a firebackand a forminate front wall integrally connected thereto by spaced ticmembers, and a burner provided with tips directed between the front andback walls.

6. A combined radiating element and fireback for gas heaters comprisingan imperforate rear wall of substantial thickness, and a forominatefront wall disposed in a rearwardly inclined relation relative to therear wall, said walls being connected by spaced tie members integraltherewith, the tie members being disposed in vertical rows, the rearwall having a plurality of spine-like projections.

7. A combined radiating element and fireback for gas heaters comprisingan imperforate rear wall, and a foraminate front wall, said walls beingconnected by spaced tie members integral therewith and disposed invertical rows.

8. A combined radiating element and fireback for gas heaters comprisinga rear wall constituting a fireback, and a reticulated front wall spacedfrom and formed integral withsaid rear wall, there being a multiplicityof integral projections in the space between the walls.

9. A combined radiating element and fire. back for gas heaterscomprising a rear wall constituting a fireback, and a reticulated frontwall spaced from and connected to said rear wall by integral spaced tiemembers.

'10. A combined radiating element and fireback for gas heaterscomprising an imperforate rear wall constituting a fireback, and aforaminate front wall disposed in spaced relation to said rear wall andconnected thereto by a multiplicity of tie members, the rear wall havinga multiplicity of projections in the space between the walls.

In witness whereof I have hereunto set my hand.

HUBERT R, HUMPHREY.
